Galilea Aranda, Pablo Andres (2016) Radiographic and ultrasonographic examinations of the horse’s stifle, in presence of flattening of the lateral trochlear ridge and effusion of articular compartments: the effect of the X-ray tube positioning in the detection of flattening in the lateromedial view variations and effect of agonistic effort in highlighting subtle ultrasonographic findings. Doctoral Thesis.
Different radiographic projections for views considered as lateromedial were examined and divided in groups. Using a method based in the Pythagorean Theorem, the distance between lateral and medial femoral condyles borders was calculated and then proportionally corrected to the diaphyseal thickness. Five categories for each axis were created and compared. Results show that radiographs with an X-Ray tube positioning within the ±5% from an exact lateromedial view in the X Axis, are statistically more effective to reveal flattenings (p<0.05).
